Airflow range adapter

Various front panel options

Deflectors for the direction of the flow pattern for models DCS/C and DCS/P

Sound attenuation options

The diffuser is of the modular type and comprise a diffuser and balancing plenum. The front panel dimensions is adapted to a modular 600 x 600 mm suspended ceiling. The front panel of the diffuser is changeable, providing different appearance options. The airflow operating range is adaptable by replacing an exchangeable airflow range adapter, independently of the diffuser size (DCS/P, DCS/C, DCS/A, DCS/J).

The duct connection has optional dimensions, for adaptation to different airflow rates.

The balancing plenum is made of galvanised steel, comprising a changeable spigot in different sizes with integral gasket for airtight duct connection.

The front panel of the diffuser is detachable for access to the balancing plenum, the airflow range adapter, ductwork and the airflow measurement and adjustment module.

DCS/P The perforated front panel of the diffuser is made of epoxy-painted steel with white (RAL 9010) as the standard colour.

DCS/C DCS/A The conical front panel of the diffuser is made of extruded aluminium, with polyester white (RAL 9010) as standard colour.

DCS/J The swirl front panel of the diffuser is made of epoxy-painted steel with a white (RAL 9010) standard colour. The swirl diffuser comprises fixed spiral blades to ensure a high mixing rate.

DCS/N The multi-nozzle front panel of the diffuser is made of epoxy-painted steel with a white (RAL 9010) standard colour. The nozzles have a two-slot design in order to ensure efficient mixing of supply air. Nozzles also are individually adjustable in order to provide high flexibility for the adjustment of the throw pattern.

The diffuser allows both appearance and performance to be changed and adapted to new requirements and operation conditions.

Halton DCS/P Air is supplied to the space through the perforated front panel and mixed into the room air outside the diffuser. The recommended maximum air temperature difference between supply and room air is -8 °C.

Halton DCS/C Air is supplied to the space through the slots of the conical front panel and mixed into the room air outside the diffuser. The recommended maximum air temperature difference between supply and room air is -12 °C.

Halton DCS/A Air is supplied to the space through the slots of the conical front panel and mixed into the room air outside the diffuser. The recommended maximum air temperature difference between supply and room air is -12 °C.

Halton DCS/N Air is supplied both horisontally and vertically to the space through the front panel of the diffuser. The supply air pattern can be radially directed in the direction(s) desired (1, 2, 3, and 4) by manually rotating the nozzles. Horisontal swirl jet and later vertical air patterns can also be achieved by adjusting the nozzles. The direction of the supply air has no effect on the pressure drop or the air flow rate. The recommended maximum air temperature difference between supply and room air is -10 °C

Halton DCS/J The horizontal radial swirl jet air is supplied to the space through the profiled spiral blades of the diffuser The recommended maximum air temperature difference between supply and room air is -12 °C. The supply air jet velocity is effectively reduced because of the high mixing effect.

Function in general

The balancing plenum equalises the air flow by reducing the flow velocity. Air is spread evenly into the diffuser, ensuring proper function. Air flow range can be adapted to the actual demand by changing the air flow range adapter, by which means proper air distribution for a wide operation range is ensured. (DCS/P, DCS/C, DCS/A, DCS/J)

The airflow rate can be adjusted by using the detachable measurement and adjustment module. The balancing plenum also attenuates duct noise. The diffuser can also be used as an exhaust unit.

As needed, the duct connection size and air flow range adapter can be changed in order to adapt the installed diffuser to a significantly reduced or increased air flow rate. Multi-nozzle diffusers do not have air flow range adapters. Instead, front panels with more or fewer nozzles are changed in this context in the stead of an air flow range adapter change.

The diffuser is connected to the balancing plenum via fastening plates and screws.

Open the front panel of the diffuser. Detach the air flow range adapter by unscrewing the four screws.

Remove the air flow adjustment module by pulling gently on the shaft (not the control spindle). Wipe the parts with a damp cloth, instead of immersing in water. The washable Dacron sound attenuation material within the plenum can be removed to enable cleaning of the inner side of the plenum.

Remount the measurement and adjustment module by pushing on the shaft until the unit meets the stop. Fix the air flow range adapter in place by screwing in the four screws. Push the front panel back into its place so that the springs lock.
